Question

I am working on pom file modifications to change the version node value. I can get xpath to modify all version nodes, but I only want it to change the version node when both the artifactId and classifier match certain values. Here is my xml:

<artifactItem>
    <groupId>com.xyz</groupId>
    <artifactId>foobar</artifactId>
    <version>${project.version}</version>
    <classifier>config</classifier>
    <type>zip</type>
    <overWrite>true</overWrite>
</artifactItem>
<artifactItem>
    <groupId>com.xyz</groupId>
    <artifactId>foobar</artifactId>
    <version>${project.version}</version>
    <type>jar</type>
</artifactItem>

If artifactId is foobar, and classifier is config, I want version returned so I can modify it.

Using other examples I found, I tried this, but it didn’t work:

/artifactItem/artifactId[.='foobar']
     /following-sibling::*
      [count(.|/artifactItem/classifier[. ='config']/preceding-sibling::*)
      =
      count(/artifactItem/classifier[. ='config']/preceding-sibling::*)
      ] 

Any suggestions would be greatly appreciated!

thanks

Answer 1

//artifactItem[artifactId='foobar' and classifier='config']/version

To explain:

We are selecting the version node, from the artifactItem node that has an artifactId of ‘foobar’ AND a classifier of ‘config’.

You use the brackets to qualify a particular node using sub-XPATH statements where the context is the node before the brackets.

Is this what you are looking for?
